Winnebago Towables User Manual page 25

Maximum Permissible Inflation Pressure -
This number is the greatest amount of air pres-
sure that should ever be put in the tire under nor-
mal driving conditions.
Tires for light trucks have other markings
besides those found on the sidewalls of passenger
tires.
LT - Indicates the tire is for light trucks or trail-
ers.
ST - Indicates the tire is for trailer use only.
Max. Load Dual kg (lbs) at kPa (psi) Cold -
Indicates the maximum load and tire pressure
when the tire is used as a dual; that is, when four
tires are put on each rear axle (a total of six or
more tires on the vehicle).
Max. Load Single kg (lbs) at kPa (psi) Cold -
This information indicates the maximum load
and tire pressure when the tire is used as a single.
Load Range - This information identifies the
tire's load-carrying capabilities and its inflation
limits.
RECOMMENDATIONS
Vehicle Load Limits
Determining the load limits of a vehicle
includes more than understanding the load limits
of the tires alone. A Federal certification label is
located on the forward half of the roadside (left)
of the unit.
The certification label will indicate the
vehicle's Gross Vehicle Weight Rating
(GVWR). This is the most weight the fully
loaded vehicle can weigh. It will also provide the
gross axle weight rating (GAWR). This is the
most a particular axle can weigh. If there are
multiple axles, the GAWR of each axle will be
provided. In the same location as the certification
label described above, there is a vehicle placard.
This placard provides tire and loading
information. In addition, this placard will show a
statement regarding maximum cargo capacity.
Cargo can be added to the vehicle, up to the
maximum weight specified on the placard. The
combined weight the cargo is provided as a single
number. In any case, remember: the total weight
of a fully loaded vehicle cannot exceed the stated
GVWR.
The weight of fully filled propane containers
is considered part of the weight of the RV before
it is loaded with cargo and is not considered part
of the disposable cargo load. Water however, is a
cargo weight and is treated as such. If there is a
freshwater storage tank of 100 gallons, this tank
when filled would weigh about 800 pounds. If
more cargo is being transported, water can be off-
loaded to keep the total amount of cargo added to
the vehicle within the limits of the GVWR so as
not to overload the vehicle.
Distribute the cargo evenly when loading to
prevent overloading front to back and side to
side. Heavy items should be placed low and as
close to the axle positions as reasonable. Too
many items on one side may overload a tire. The
best way to know the actual weight of the vehicle
is to weigh it at a public scale. Talk to your RV
dealer to discuss weighing methods needed to
capture the various weights related to the RV.
This would include weights for the following:
axles, wheels, hitch or pin (in the case of a trailer)
and total weight.
